OEsophagus

OEsophagus, or Gullet, connects the lower part of the pharnyx with the cardiac orifice of the stomach. It is about 9 inches long, and is lined internally with mucous membrane, beneath which is the submucous tissue containing glands, and external to this a muscular coat. The muscles of the oesophagus by their wave-like contraction convey the bolus of food received from the pharynx into the stomach.
